1. The vitamin that is soluble in water is (b) Vitamin B. Water-soluble vitamins dissolve in water and are not stored in the body to the same extent as fat-soluble vitamins. Vitamin B includes various B vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine)Read more

    The vitamin that is soluble in water is (b) Vitamin B. Water-soluble vitamins dissolve in water and are not stored in the body to the same extent as fat-soluble vitamins. Vitamin B includes various B vitamins such as B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin). These vitamins play crucial roles in energy metabolism, nervous system function, cell metabolism, and the formation of red blood cells. Excess water-soluble vitamins are usually excreted in urine, so regular intake through diet or supplementation is essential.

  2. The daily energy requirement of a hardworking man varies based on factors such as age, weight, height, physical activity level, and metabolism. However, a rough estimate for a hardworking individual engaged in strenuous activities might range between 3500 Kcal to 4000 Kcal per day. This higher energRead more

    The daily energy requirement of a hardworking man varies based on factors such as age, weight, height, physical activity level, and metabolism. However, a rough estimate for a hardworking individual engaged in strenuous activities might range between 3500 Kcal to 4000 Kcal per day. This higher energy requirement is necessary to fuel the increased metabolic demands associated with vigorous physical work. It’s crucial for such individuals to consume a balanced diet rich in carbohydrates, proteins, healthy fats, vitamins, and minerals to meet their energy needs and support overall health and performance. Regular monitoring and adjustment of dietary intake based on activity levels and energy expenditure are recommended to maintain optimal health and performance.

  3. Another name of Vitamin B2 is (c) Riboflavin. Riboflavin is a water-soluble vitamin essential for various bodily functions, including energy production, metabolism, and maintaining healthy skin, eyes, and nervous system. It plays a crucial role in converting carbohydrates into energy and acts as anRead more

    Another name of Vitamin B2 is (c) Riboflavin. Riboflavin is a water-soluble vitamin essential for various bodily functions, including energy production, metabolism, and maintaining healthy skin, eyes, and nervous system. It plays a crucial role in converting carbohydrates into energy and acts as an antioxidant, protecting cells from damage caused by free radicals. Riboflavin is commonly found in foods such as dairy products, meats, leafy green vegetables, and enriched cereals. Deficiency in riboflavin can lead to symptoms such as skin disorders, inflammation of the mouth and tongue, and decreased red blood cell count.

    The disease of sickle cell anemia is caused due to the abnormality of (b) Red blood cell. It is a genetic disorder characterized by the presence of abnormal hemoglobin, specifically hemoglobin S. This mutation causes red blood cells to assume a rigid, sickle-like shape under certain conditions, leading to blockages in blood vessels, reduced oxygen delivery to tissues, and various complications such as pain crises, organ damage, and anemia. Unlike white blood cells (a), platelets (c), or blood plasma composition (d), which play essential roles in immune response, clotting, and maintaining blood volume, sickle cell anemia primarily affects the structure and function of red blood cells.

  5. The infectious stage of malaria is (d) Sporozoite. Sporozoites are the form of the malaria parasite transmitted to humans through the bite of infected mosquitoes.

    The infectious stage of malaria is (d) Sporozoite. Sporozoites are the form of the malaria parasite transmitted to humans through the bite of infected mosquitoes. When an infected mosquito bites a person, it injects sporozoites into the bloodstream. From there, sporozoites travel to the liver, where they invade liver cells and multiply, initiating the infection cycle. After replication in the liver, sporozoites develop into merozoites, which are released into the bloodstream, infecting red blood cells and causing symptoms of malaria. Thus, while merozoites are responsible for the symptomatic phase, sporozoites initiate the infection by entering the host’s bloodstream.
